Steering is now fixed I have another issue today

ed in cny · #1 06-10-2016, 06:53 PM

I got the steering in the tractor and it works real well with that new steering upgrade kit. Acts like power steering almost as other say it does. Like it. Keeping an eye on the cam follower.

Issue today is transmission. Something went when I was mowing. First off this is a 124 with a creeper gear. Yesterday I had the mower belt go bad. It jumped off the front guide pulley under the PTO. Hence it eat it up rather quickly. I replace the belt and got back to work today.

I got back to mowing some ground that was a bit tall. I has mowed it in high setting the other day and wanted to trim it down lower. Got it almost done and the creeper gear wouldn't go into gear. It went in after a bit of clutching and back and forth with the creeper. Finished up what I needed to mow. Put it hi on the creeper and when to another place to mow. Got there and again another place I needed to be in lo on the creeper. It didn't do anything. No forward no back. HI or Lo nothing.

I took off the mower deck and got underneath the tractor to have a look. I see that the creeper is covered with dirt and oil. It's been there and like that for some time. Can't see it leaking anywhere but know it has at some time. I see a spot that looks like a place you test for fluid but can't see where you could fill it.

I'm lost as to what it could be. If I put it into gear and push it, it free wheels like it isn't in gear. The tractor runs great otherwise. Am I looking at a creeper gear rebuild? If so what does that entail? What else if I have to get deep into this repair should I be also looking to correct? Where do I start to diagnose this issue?

Help guys I have more to mow.

Check for a sheared spirol pin in your driveline.

First thing I would check too.

Not sure what I am looking for. I looked the underneath over but didn't see anything out of the norm. Evreything looked in place. I had trouble getting it to engage with the clutch in. Just ground. So I'm thinking either creeper or possibly the clutch. If I know where this spirol pin I'll check this too.

Looked up the creeper repair and it's a bit of work. I'd have to split the tractor to get at it. Hope this pin is the answer.

Spirol pins will break, but look fine because it broke inside. So the pin could possibly be in three pieces.
Did you look in the service manual for drive line? Or Cubcadet.com for exploded view of the driveline?
And yes, you pretty much need to split the tractor for creeper repair.

Ok as best I can guess the spiral pin is on the creeper shift arm. But where? I looked up the diagram on the link you posted but the pin is not numbered or shown. The creeper shifts forward and back and I see movement through to the clip that holds it in hi or lo. So this pin is somewhere from the knob to through the housing to the other side? I'd check if I am sure I am looking in the right spot.

I really am glad for the help guys just frustrated I have had so much go wrong this year with this old girl. It's been a great little tractor as long as I have had it. I guess the statement "nothing ever goes right with a tractor sitting" pretty much sums it up for me this year. No snow to use it for the first time in 50 years in CNY and she sat. Guess after this there isn't much left to repair. If I get into doing a split I guess I'll have to start another post on a resto, fast and dirty but a resto of sorts. Oh well I guess I'm in it this far might as well see where this takes me.

Never seen 1 in person, but they are not talking about the shift mechanism itself. It looks to me that theres a coupler coming out of the creeper gearbox that's connecting the driveshaft to the clutch. that's where, it appears to me, the spirol pin should be? they look just like a roll pin. Spring pin? Can't think of another term for it. I would look there at the coupler if it was me. There might be an input shaft that's visible also? Looks like it may have spirol pins as well but that's just a guess. I have only worked on my 149 hydro so haven't a clue what yours looks like other than the pic in the manual. HTH Matt

There is a pin in each end of the driveshaft. One in the coupling that is on the creeper gear. One in the driveshaft to the creeper coupler and one at the front that connects the clutch disc.

The two at the back end of the driveshaft are spirol pins and even if they shear, you can't tell by looking. You have to turn the driveshaft and watch the creeper gear coupler and input shaft to make sure you get the same rotation. Same way with the clutch plate end of the driveshaft. Make sure the creeper is engaged when you do this.

The driveshaft in a gear drive has spirol pins at the clutch plates and at the coupler(s). If any of those shear, it will not be obvious with just a glance.

Here is a full length driveshaft, all of those holes use spirol pins.

This is a coupler to connect the driveshaft to either the transmission or the creeper gearbox

It is possible you tore up the end of the creeper gear input shaft. I can fix that if that happened ( not very common )

Another possible failure would be the cotter pins sheared on the creeper gear hi/low gear change lever. ( not common either )

All good responses but I will share my experience. I had this happen recently on my 122 with exactly your symptoms. Creeper was in between ranges and Ended up being the roll pin worked it's way down out of the shift collar inside the creeper. You can fix this without splitting the tractor if this is what happened. You have to verify though like others have said that the creeper input is turning with the drive shaft. You can take the drain out of the creeper and put the punch up through the drain hole to hit the pin back in but it's difficult to line up and patience is necessary.
